Willing had painted his face in camouflage and had a loaded shotgun tucked into his pants, according to the release.

Janesville police Lt. Keith Lawver said Willing confessed he held up the Walgreens Tuesday night while showing a gun, then stole prescription drugs. Willing told police he's addicted to narcotics, and said he'd planned rob the same Walgreens again early Wednesday to get more prescription drugs, Lawver said.

Lawver said it's odd Willing would have tried to rob the same business only hours later.

"It's definitely not common that someone would go and hit the same place two days in a row," Lawver said.

Willing was being held on tentative charges of robbery, attempted robbery, theft and carrying a concealed weapon, according to the release. He is expected for an initial appearance in court Thursday.
